Motherboard has integrated sound already. You really don't need one unless you're an audio freak.
Oh okay, sweet. I'm learning quite a bit from this whole process, lol.
Y'know, I just realized that I don't know how to assemble it when it all gets here. I know how to put in the memory, HDD, CD/DVD drives, PSU (I think), but past that, I don't really know. Is there any soldering involved?
